First of all I'd be VERY suprised if NCL does anything with the Big U. Most people are under the assumption that she and the Indy were purchased as an 'insurance policy' to make sure no other company grabbed them while NCL America was starting-up and thinking that they were going to corner a new market. Secondly, if by a miracle that NCL pulls off the unthinkable and starts refurbing her I seriously doubt her original powerplant is going to be retained. After Norway's accident, no corporation is going to take a gamble on boilers that are 50+ years old. The company simply can't afford NOT to re-engine the ship. Unfortunately this is business logic behind all these things and as we all know they never go hand-in-hand with the historians, fans and the like.
